Can you really get a useful scope for $25? What's it like?
It's 30 Mhz dual-trace analog Tek scope, a bit fuzzy looking. But it gets the point across that you don't need a high-end scope to do these measurements, just basic skills and thought.
Here's someone who made the hard-drive scope before me: http://hackedgadgets.com/2006/06/01/making-a-hard-drive-laser-oscilloscope/ Mine has is good up to about 300 Hz. http://www.youtube.com/user/wa5znu#p/a/u/1/m8D_6AIS7eo Leigh/WA5ZNU _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
